Der Schmerz
-
The present article is a case report on a chronic sympathetically maintained pain syndrome following a mild lesion of the brachial plexus. Apart from slight motor and sensory disturbances, which disappeared within a few months, no autonomic, motor or sensory deficit remained. ⋯ In the climax of the pain attacks it became manifest like a mirror reflexion on the opposite side. The diagnostic and therapeutic problems that occurred during these years and the dependency of the pain attacks on exterior influences are evaluated.
